Application: filed July 19;

Mens and boys hats arestacked by manu .facturers in cardboard boxes forstoring and transportation, to dealers, the lowest hat of.

. the stack'being set into a cardboard stay stays.

,with'its brim re'sting upon and supported by the rim of; the stay. Theupper edges of the stays are bent over. to form widened bearings for thehat brims torest upon.'

This invention relates to a process of and machine for curling theupperedges of hat incident to handling and transportation, will a bepractically eliminated.

This object is attained by providing a ma- I chine with frustro-conicalrolls-and a curler to which the stays may be presented by an hold theperiphery of theeupper roll adjaoperative and the edges of the cardboardfirst stretched to obtain the necessary in crease in diameter, and.'then, without removing the stays or interruptingthe operation thestretched edges may be curved into wide smooth curls which will supporthats without chafing the brims.

In the accompanying drawings Fig.1 shows a side elevation of a machinethat em bodies the invention and by which the process may be practiced,with the frame cut in section. Fig. 2 illustrates on larger scale. thefirst or stretching action of the rollson the cardboard stay. Fig. 3illustrates the following or curling action. Fig. 4 is a plan ofthecurler which is used. Fig. 5 is a front elevation showing therelation of the curler to the conical rolls. Fig. 6 on reduced scaleshows a section of a stay before it is operated upon according to thisinven tion. Fig. 7 shows a section of a stay in. its completedcondition. I

Themachine which is illustrated for carrying out they process has aframe or casing 1 desirably cast to shape with means for supporting itupon a bench or table. Supported by hearing sleeves 2 and 3 fixed in thelower part of the frame is a shaft 4 that at its rear end has a drivingpulley 5. Se-

cured to the front end of this shaft is a 1927. Serial No. ace-s21.

roll 6 that has an inwardly tapering periph oral surface?- and'acylindricalperipheral surface 8 of smaller. diameter than and at theroar of the tapering surface of the roll.

,Fastened to theshaft 4: is a gear 9 meshing with which is a gear 10fastened to a shaft 11 on thefront end of which is a conical roll 12.This roll 12-has an outwardly tapering peripheral surface 13. and anarrow cylindricalperipheral surface 141 on its inner side. The shaft 11is fitted in a bearing 'sleeve 15 that is held in a block 16 which ispivoted in an opening'in the rear wallof "the framevbytrunnions17. Thefront end of the upper shaft is fitted inj' a bearing sleeve 18 which isheld bya block 19 that is, free to move up and down in an. opening inthe front wallof the frame. A spring 20 isarrangcd between the block andthe fra me to normally lift this end of the shaft 11 and hold the roll13 raised. plunger .21 is placed in the top of the frame'so as to engagethe block 19. A lever 22 pivoted on the stud 23 fastened on top of theframe is arranged to press the plunger down and cent to the peripheryof'the lower roll when the machine is being used 7 1 Fastened to theframe with'its' line with andclosefto the adjacent periph r eralsurfaces ofithe upper and lower rolls til) both rolls are rotated. Theupper edge of the stay blank which is a conical tube of cardboard isdipped into warm water which softens it to an extent, andthis Wet edgeis inserted bythe operative a short distance between the rolls,yand' theupper roll, by means of the lever is brought down so as to compress thewet edge of the stay between the' rolls. .The conical-rollsrotaterapidly and the stay'rolls around with-them. The first few rotations ofthe rolls stretches the edge of the paper so that this edge assumessubstantially the relation to the bodyofjthe stay that is indicated at27 in Fig. 2. When "ing the wide curl on the edge, as indicated in F igQ3. When the curl is completed the upper roll is allowed to rise and thestay is removed. The action of the rolls is 0on tinuous, they, as thestays are presented by the operative, first stretch the edges and thenas the operative advances the stays between the rolls the wet stretchededges are curled. Bythe practice of this method and with such a machineas described large smooth curls {can be very rapidly produced on theedges of the stays.

The invention claimed is "1'. A machine for curling hat stays comprisinga frame, a shaft rotatably supported in bearings fixed in the frame andcarrying 'a -gear and a tapering roll, a shaft rotatably roll, rotatablysupported in bearings fixed in the frame, a shaft carrying a taperingroll,

su orted in bearin s iivoted in the frame and carrying a gear and atapering roll, said gears intermeshing and said rolls taperingreverse'ly, means for swinging the pivotally supported shaft and movingthe roll which itcarries toward and from the other roll, and a curlerattached to the frame and loca-ted to curve the edge of a stay back ofthe opening between the peripheries of the rolls.
